Magnetism that results from an electric current
Anything that uses electricity to operate. (light bulb, computer, etc.)
A device for making, breaking, or changing the connections in an electrical circuit.
Any living thing
a characteristic that is passed from parent to offspring
a producer of offspring
The entire span in the life of an organism from one generation to the next.
A unique feature of an organism that best helps it survive in its environment.
A group of individuals that belong to the same species and live in the same area
a magnet made from a material that easily loses its magnetism, such as an electromagnet.
A collection of electrons. The charges don't move.
(Physical) Characteristics of a substance that can be observed, measured, or changed and used to identify matter.
A magnet made of material that keeps its magnetism
produces electricity in a circuit, such as a battery or generator.
The path that electrons flow through from power source to load and back again. Usually the pathway is made of wires.
The area of magnetic force around a magnet
The attraction or repulsion between magnetic poles
Process in which sediment is laid down in new locations.
Anything that has mass and takes up space
A large mass of moving ice and snow on land
A state of matter with no definite shape or volume
A material that allows electricity to pass through it.
A form of matter that has a definite shape and volume
The path of an electric current from the power source through conductors to the load and back to its original source.
A device that produces electricity
A state of matter that has a definite volume but no definite shape.
Any material that produces a magnetic field.
The organization of earth history into time: eras, periods, and epochs.
A device that uses Earth's magnetic field to attract a free floating needle to point North.
A measure of the force of gravity on an object
to push away
inherited behaviors of an organism.
A material that does not allow electrons to move through it easily.
To pull together
any difference between individuals of the same species. Variations cause adaptation among species when advantageous variations survive and organisms without it die off.
a rise of land to a higher elevation (as in the process of mountain building)
A chemical substance formed as a result of a chemical reaction
A change in a substance that does not involve a change in the identity of the substance. (no new substance is formed)
A change in matter that produces one or more new substances. An unexpected change (for example state of matter, energy, color, or light)
a behavior that has been learned from experience or observation. NOT inherited from parents.
A trait that is not in your genes but is picked up from enviornmental factors
The continuous flow of electrons in a complete circuit.
a circuit whose path is broken
a magnet that is produced naturally and made of minerals (magnetite or lodestone)
All of the non-inherited surrounding things, conditions, and influences affecting the growth or development of living things.
A group of similar organisms that can produce offspring.
a new organism produced by one or more parents
Characteristics of an organism
Process by which individuals that are better suited to their environment survive and reproduce most successfully; also called natural selection.
openings in Earth's crust from which molten rock, dust, ash, and hot gases flow or erupt (cinder cone, shield, and composite)
The breaking down of rocks and other materials on the Earth's surface.
A flat topped rock or hill formation with steep sides
a rock formation with the softer, inner rock eroded leaving a bridge-like formation.
Shaking and vibration at the surface of the earth resulting from underground movement along a fault plane of from volcanic activity
Processes by which rock, sand, and soil are carried away after being broken down (weathered)
Cracks in the Earth's crust where plates grind/slide past each other
A measure of the amount of matter in an object
A measure of the size of space matter takes up
A starting material in a chemical reaction
A property of some materials in which there is a force of repulsion or attraction between certain like and unlike poles
Energy that is transformed as a consequence of temperature differences
A single kind of matter that is pure
